More than 20 projects already run on HesaBase.

Frequently asked questions

What does a project cost?

That depends on the scope. After the initial consultation you receive a written quote with a fixed price or a clear cost range.

How long does it take?

A website is often ready in a few weeks. Apps and platforms with accounts and payments usually take two to four months.

Who owns the source code and data?

Usage rights, source code handover and hosting are agreed in writing in the contract beforehand – transparent and traceable.

Does my website have to be accessible?

Since June 2025, the European Accessibility Act – the BFSG in Germany – requires many online services to be accessible. We check whether it applies to you and implement it.

Do you work with clients abroad?

Yes. We work in German and English, and your application can appear in as many languages as you need – just like this website.

Do you take over existing projects?

Yes. We review existing apps and websites, fix bugs and bring them to a secure, maintainable state.

Tell us about your project.

Free and non-binding. You will usually hear back within one business day – directly from the developer, not from a sales team.
